Android Studio版本中实现上拉下拉自动刷新功能的控件及其示例代码

This project aims to provide a reusable Pull to Refresh widget for Android. It was originally based on Johan Nilsson's library (mainly for graphics, strings and animations), but these have been replaced since. Features Supports both Pulling Down from the top, and Pulling Up from the bottom (or even both). Animated Scrolling for all devices. Over Scroll supports for devices on Android v2.3+. Currently works with: ListView ExpandableListView GridView WebView ScrollView HorizontalScrollView ViewPager Integrated End of List Listener for use of detecting when the user has scrolled to the bottom. Maven Support. Indicators to show the user when a Pull-to-Refresh is available. Support for ListFragment! Lots of Customisation options!
